    摘要
  • 摘要: 人工冻结技术在深部地下工程施工中的广泛使用，使人们更加迫切地认识到对深土冻土力学研究的必要性。本文 通过分析目前国内外对深部岩土工程的认识，在前人对深土及深土冻土理解的基础上，考虑深土冻土形成过程的特殊性及受力特点，从新的角度给出了深土冻土及深土冻土力学的概念，阐述了深土冻土力学的主要研究内容。最后通过对深土冻土力学研究现状的分析，从深土冻土室内物理力学试验研究、大型模型模拟研究、理论模型研究以及工程应用等四个角度讨论了目前室内进行深土冻土力学研究所面临的主要问题。
    Abstract: As artificial freezing technique has been widely used in the deep underground construction, more and more people have become aware of the necessity to carry out researches on mechanics of the deep frozen soils urgently. By analyzing the worldwide understanding of deep geotechnical engineering and previous understanding of deep soils and deep frozen soils, a new conception system is provided for the deep frozen soils and mechanics of the deep frozen soils considering the special characteristics of the formation process and stress of the deep frozen soils. The research content and methods are discussed to study the mechanics of deep frozen soils, and the developing status quo of the mechanics of deep frozen soils is presented. Finally, some urgent problems to be solved in this study task are put forward in terms of laboratory physical and mechanical tests, large-scale model simulations, theoretical model and engineering applications of deep frozen soil.
